近几年来在低渗透油藏开发的理论研究中出现了一些对科学概念理解出现误区和不分条件类比应用概念和公式的情况,澄清了低渗透和特低渗透储层渗流存在应力敏感性和启动压力、固体岩石和流体流变以及低速流体多孔介质中渗流的科学概念,并从理论上分析了理解误区出现的原因,证明了低渗透储层存在强的应力敏感性,特低渗透储层低速渗流存在启动压力,不再服从达西定律。
In recent years, some theoretical studies on the development of low-permeability reservoirs have shown some misunderstandings about the concept of scientific concepts and the application of concepts and formulas regardless of the conditional analogy. It is clarified that there is stress sensitivity in the seepage of low and ultra-low permeability reservoirs and Start-up pressure, solid rock and fluid rheology, as well as the concept of seepage in low-velocity fluid porous media, and theoretically analyzed the reasons for the misunderstanding, prove that there is a strong stress sensitivity of low permeability reservoir, ultra-low permeability reservoir There is a starting pressure for low velocity seepage and no longer subject to Darcy’s law.
